Duct Insulation, 1-1/2In x 48In x 25Ft

Quality insulation!!

Seemed like great deal. Used to repair duct work. Came in large box, Wide roll. 3M venture tape went over it and stuck to it well. Easy to cut with fresh razor blade. I would buy this again if the seller can't maintain this competitive price. Otherwise I will have to return to buying it local. Convenient to have Amazon deliver it at this competitive price.

Very easy to work with, no concerns just seems less extreme than the pink insulation

Product came well packaged with no damage. I used it to wrap the exposed ductwork branches from main trunk. The heat discharge temp at the registers has increased by about ten degrees. It is very easy to measure and cut and tape. Wear safety glasses and dust mask if working overhead especially as there is some fiber that that gets loosened when you work with it.

Wonderful for Insulating the Hose on Whynter Portable Air Conditioner - man, what a HUGE difference! I was wondering why I was feeling heat when I had the A/C on and it was definitely blowing cold air. I went to check the unit and felt heat coming from somewhere. It was the coming through the walls of the exhaust hose. Grrrrr. This insulation wrapped around the hose and secured with metal heat tape does an incredible job of blocking the heat.

I needed to air seal and re-insulate my hvac plenum in my attic. I initially bought a roll of FrostKing insulation from Lowe’s, but it was garbage, really weak stuff. However, this stuff is professional grade insulation. The silver backing is tough and reinforced with fiberglass strings, and both foil and cloth tapes adhere to it very well.

Doubled up my insulation on my dockwork since it in the attic. Keeps the air cooler when ac turns on

I bought an investment property that had rodent damaged ductwork. Main trunk line (15" metal and feeder line 8"). HVAC company wanted to charge me over a grand and I had to wait 6 months. I purchased this item along with a 4" foil tape, 3" mesh tape and a gallon of mastic and 4-6 hours later I was able to clean the old, re-secure and reseal the metal duct then wrap with this product and finish the job off with mastic to seal the seams. In case you're wondering the size diameter pipe it will fit multiply the diameter of your pipe by pi (3.14) and you'll get the circumference (mine was 15 x 3.14=47.1, exact fit for this 48" sheet). Saved me quite a bit of money and I lost 10 pounds working in the attic for 5 hours.
